Jacksonville police said Dunn asked a group of teens that included Davis to turn down their music, but after a fight ensued Dunn fired eight or nine shots in to the vehicle and took off with his girlfriend.

Witnesses jotted down Dunn's tag number leading to his arrest, according to officials.

At his first appearance Monday, Dunn pleaded not guilty to charges of murder and attempted murder and his lawyer would not give a specific reason why Dunn took off.

Criminal defense attorney Richard Hornsby, who has successfully argued self-defense cases under Florida's controversial Stand Your Ground Law, said Dunn will have a very difficult time explaining to a judge why he felt the need to fire multiple times then flee without contacting law enforcement.

"This Jacksonville case does not scream 'self-defense' to me," said Hornsby. "It screams reckless behavior. It screams that a person wasn't using his better judgment."
